WARNING: This page is about a different variant/trim than selected.

NOTE:

Be careful that the foreign matter is not into or onto the assembled component during installation.
Apply engine oil to all component parts of the timing chain.

Install timing chain LH. < Refer to TIMING CHAIN LH , INSTALLATION, Timing Chain Assembly. >
Prepare to attach the chain tensioner RH.
1. Move the link plate (A) in the direction of arrow to press in the plunger (B).

2. With a 2.5 mm (0.98 in) dia. stopper pin or a 2.5 mm (0.98 in) (nominal) dia. hex wrench inserted into the stopper pin hole, secure the plunger.
  NOTE: If the stopper pin hole on the link plate and the stopper pin hole on the chain tensioner are not aligned, check that the first notch of plunger rack (A) is engaged with the stopper tooth (B). If not engaged, retract the plunger a little so that the first notch of plunger rack (A) is engaged with the stopper tooth (B).
